Sven Leyffer is an internationally recognized leader in numerical optimization, with major accomplishments in three distinct hot-topic areas: nonlinearly constrained optimization, mixed-integer nonlinear optimization, and optimization problems with equilibrium constraints. In all three areas, he has made fundamental contributions to the theoretical foundations; developed state-of-the-art methods and robust implementations; and promoted novel applications, many of pivotal importance to the DOE.

David F. Brown has been with Argonne since 1993 and is a principal investigator in projects that include the modeling of chemical and biological agent releases in subways and interior facilities; modeling the release and atmospheric dispersion from chemical accidents; and quantitative risk assessment for hazardous materials transportation.

Lois Curfman McInnes is a computational scientist who develops innovative numerical methods and software for the solution of large-scale systems based on nonlinear partial differential equations. Her interests include multiphysics simulations and software interoperability.

Susan Coghlan, deputy division director at the Argonne Leadership Computing Facility, is a Linux cluster expert and systems integration professional who has worked on high-performance parallel and distributed computers for more than 20 years.

Marc Snir is an Argonne Associate and former director of Argonne's Mathematics and Computer Science Division. His research focuses on high-performance computing, with recent work on programming models, tools, and performance analysis.

Michael Papka is a data visualization expert whose current research interests involve the management, processing and analysis of scientific data. He is director of the Argonne Leadership Computing Facility, which houses an IBM Blue Gene/Q supercomputer.
